BreakdownBuilt specifically for the GravityWorks water filter system, but you can attach this filter between water bladders you already have. It works great for anyone looking for a lightweight, gravity-fed water purification system in the backcountry. Just hook it between your dirty and clean water bladder and hang it up while you do other things like glassing or getting camp set up. It also allows you to double the water you can carry and then filter it when it's convenient.
